Abstract

The present invention relates to the cold adhering and sewing method of repairing torn conveyer belt with steel cable core. The repairing process includes cutting and leveling the edge of the torn part, cutting small inclined planes constituting two opposite V-slots along the steel cable, drilling through holes in the positions apart from the edge of the belt by 2-5 steel cable intervals, connecting the torn belt sections mechanically with 8-shaped steel cable buckle and final casting with high strength flexible glue to cover all notches.

Description

Steel cable core conveying belt is torn the method that damaged back adopts cold adhering and sewing to repair

The invention belongs to the technological improvement that conveyer belt is repaired, be specifically related to a kind of steel cable core conveying belt and tear the method that damaged back adopts cold adhering and sewing to repair.

Be commonly used owing to steel cable core conveying belt tensile strength height, wear-out life are long, the grooving performance is good, but should band since broadwise (width) intensity a little less than, meeting damage because of tearing when careless using.At present, to the belt of tearing, re-use after adopting raw stock heat cure technology to repair more, be that equipment investment is big, the operating time is long, cost is high but adopt the shortcoming of heat cure technology reparation, can't repair on a large scale, difficulty has realized repairing the purpose that old profit is is newly increased income and decreased expenditure.

The objective of the invention is problem, provide a kind of steel cable core conveying belt is torn the method that damaged back adopts cold adhering and sewing to repair at above-mentioned existence.

For achieving the above object, the present invention is realized by following technical step:

1, the neat and suitable steel wire rope of belt edge sanction that at first will tear partly is cut into little inclined-plane, makes two miters of correspondence become the big V-type groove of drift angle;

2, rule along the band direction at 2～5 steel wire rope places of distance belt edge, and make a call to a small through hole, and be cut into little V-type communicating groove with hilt small through hole and little inclined-plane every 50～150mm;

3, with 8 font wire line hitch mechanical attachment is carried out in two film band alignment of the major-minor of tearing;

4, all treating such as large and small V-type groove being connect face pours into a mould with the high-strength flexible covering rubber for preparing;

5, vulcanizing treatment, normal temperature～150 ℃/12～0.5h.

Advantage of the present invention: the one, abandoned conventional method by gluing connection, changing the framework material that utilizes earlier in the conveyer belt into---wire line hitch carries out mechanical connection, back way, thereby the effect that intensity after realizing repairing and former belt body intensity are complementary with the bonding filling of special high-strength flexible covering rubber; The 2nd, prosthetic appliance is simple, and easily repair the time and labour saving, both can construct at the scene, can construct the disposable reparation that can finish up to a hundred meters again in the special manufacturer; The 3rd, cost is low, easily promotes, and the cold adhering and sewing reparation only is 1/3rd of a hot sticky rehabilitation cost.

Below in conjunction with accompanying drawing the embodiment of the invention is elaborated.

Figure one is a structural representation of the present invention.

Figure two is generalized sections of wire line hitch.

Shown in figure one, two, steel cable core conveying belt is torn the method that damaged back adopts cold adhering and sewing to repair, be that little inclined-plane is cut out together and be cut in the belt body edge that will tear part earlier along steel wire rope, after being coincide, corresponding two little inclined-planes of belt of major-minor become the big V-type groove of drift angle (1), inside 2～5 steel wire ropes of belt edge (3) are located, beat small through hole (2), and small through hole and the little inclined-plane of band edge are linked up with little V-type groove (4).After said structure is finished, two belts of major-minor are coincide by dimensional requirement, and with 8 font steel wire ropes (6) with buckle (5), pass, carry out fastening through little V-type groove (4) from small through hole (2).After two belts of major-minor carried out mechanical connection, all big or small V-type grooves were waited for maxxaediums surface treatment of all polishing, and pour into a mould all hole recesses with the high-strength flexible covering rubber for preparing at last and carry out vulcanizing treatment, conditions of vulcanization: normal temperature～150 ℃/12～0.5h.

Claims

1, a kind of steel cable core conveying belt is torn the method that damaged back adopts cold adhering and sewing to repair, it is characterized in that: the belt edge of tearing is cut into little inclined-plane after cutting out together, make two corresponding miters become the big V-type groove of drift angle (1), locate to be equipped with small through hole (2) from inside 2～5 steel wire ropes of belt edge (3), and small through hole (2) and the little inclined-plane of band edge linked up with little V-type groove (4), use special wire line hitch (5) two adhesive tapes of major-minor to be coincide then by small through hole (2) and little V-type groove (4), and carrying out mechanical attachment, drift angle V-type groove (1) and little V-type groove (4) carry out vulcanizing treatment after waiting all waiting to connect the interior cast of face high-strength flexible covering rubber.

2, steel cable core conveying belt according to claim 1 is torn the method that damaged back adopts cold adhering and sewing to repair, it is characterized in that: special wire line hitch is made up of button (5) and seizing wire (6) two parts, button is the tubular metal thing, seizing wire passes in manage and is 8 fonts, when with seizing wire from small through hole (2) with after little V-type groove (4) is connected two adhesive tapes of major-minor, just with special mould buckle is flattened, make the seizing wire locking that penetrates in it.

3, steel cable core conveying belt according to claim 1 is torn the method that damaged back adopts cold adhering and sewing to repair, and it is characterized in that: the condition of the belt vulcanizing treatment after bonding, normal temperature～150 ℃/12～0.5h.
